RELATED APPLICATION

This application is a U.S. National Stage of PCT International PatentApplication No. PCT/US2013/031468, filed Mar. 14, 2013, which claims thebenefit of and priority to U.S. Provisional Patent Application Ser. No.61/716,176, filed Oct. 19, 2012, both of which are incorporated byreference herein.

FIELD OF THE DISCLOSURE

The present disclosure is generally related to intermittent cathetersfor use in draining urine from the human bladder and, more particularly,to intermittent urinary catheter assemblies for use by those facingcatheter drainage issues such as wheelchair bound users and the like.

BACKGROUND OF THE DISCLOSURE

Intermittent catheterization is a good option for many users who sufferfrom various abnormalities of the urinary system. A common situation iswhere a single use, individually packaged, sterile catheter is used. Animportant criterion for any single use product is that it be userfriendly since there will often not be trained medical personnelperforming catheterization.

Due to the advancements that have been made in intermittent urinarycatheter products, it is now quite common for users who requirecatheterization on a recurring basis to perform this procedurethemselves. The intermittent urinary catheter products which arecurrently available render the catheterization procedure straightforwardfor many catheter users. However, this is not the case for some userssuch as those who are wheelchair bound who may encounter difficulty inbeing able to discharge urine from an intermittent urinary catheterdirectly into a toilet.

For wheelchair bound users who would otherwise be able to administerself-intermittent catheterization for voiding their bladder of urinemultiple times per day, existing intermittent urinary catheter productshave not provided a suitable solution for discharging urine from thecatheter into a toilet, especially for allowing the users to remain intheir wheelchair in close proximity to the toilet during thecatheterization procedure without concern for urine spillage.

SUMMARY OF THE DISCLOSURE

There are several aspects of the present subject matter which may beembodied separately or together in the devices and systems described andclaimed below. These aspects may be employed alone or in combinationwith other aspects of the subject matter described herein, and thedescription of these aspects together is not intended to preclude theuse of these aspects separately or the claiming of such aspectsseparately or in different combinations as set forth in the claimsappended hereto.

In the present disclosure, an intermittent urinary catheter assemblycomprises a catheter tube having a proximal insertion end and a distalend remote from the proximal insertion end. The catheter tube has alumen which extends from at or near the proximal insertion end to thedistal end for draining urine from a human bladder. The catheter tubealso has at least one drainage opening which extends through thecatheter tube to the lumen at or near the proximal insertion end. Thecatheter tube further has a discharge opening which is associated withthe distal end thereof to permit urine from a human bladder to bedischarged. The urine is discharged through the discharge opening in thecatheter tube after it has first passed from the human bladder, throughthe drainage opening, and through the lumen of the catheter tube.

The intermittent urinary catheter assembly includes a urine dischargesleeve associated with the discharge opening. The urine discharge sleevehas a compact stowed configuration and is extendable to a deployedconfiguration for directing urine to for example a receptacle, such as,a toilet at a location spaced from the catheter tube. In the compactstowed configuration, the urine discharge sleeve may be concertina orreverse folded or rolled. Optionally, the catheter tube has a protectivesleeve covering at least a portion thereof for non-contaminatedinsertion while extending the proximal insertion end through a urethrauntil it is disposed within the bladder for urine drainage.

In one exemplary embodiment, a funnel is associated with the distal endof the catheter tube and defines the discharge opening wherein the urinedischarge sleeve may have a first end secured to the funnel and asecond, extendable end. Advantageously, the urine discharge sleeve maybe concertina folded about the funnel, and a discharge funnel may beprovided for extending the second end of the urine discharge sleeve.Alternatively, the urine discharge sleeve may be reverse folded andsecured to the funnel utilizing a paper band, and a pull ring having anadhesive area may be secured to the second end of the urine dischargesleeve.

In another exemplary embodiment, a funnel is again associated with thedistal end of the catheter tube and defines the discharge opening, butin this embodiment the urine discharge sleeve may have a first endsecured to a fitting or nipple and a second, extendable end. The urinedischarge sleeve may be concertina folded and disposed within adischarge funnel, or reverse folded and secured to the adapter by apaper band and, in the latter embodiment, a pull tab having an adhesivearea thereon may suitably be secured to the second end of the urinedischarge sleeve. Further, these embodiments may suitably compriseadapter assemblies where the fitting or nipple is adapted to be insertedinto the funnel following which the second end of the urine dischargesleeve may be extended away from the funnel to a receptacle, e.g., atoilet.

Thus, the present disclosure is also directed to an adapter assembly forextending the point from which urine from a human bladder can bedischarged from any conventional intermittent urinary catheter. Theadapter assembly comprises a fitting or nipple having an axiallyextending urine passageway for insertion into the discharge opening at aurine discharge end of the intermittent urinary catheter. The adapterassembly may include a discharge funnel associated with, but separablefrom, the nipple, and a urine discharge sleeve within the dischargefunnel which has a first end secured to the nipple and a second endsecured to the discharge funnel. With this arrangement, the dischargefunnel is separable from the nipple for extending the urine dischargesleeve so the discharge funnel can be positioned for urine discharge ata distance from the nipple.

DETAILED DESCRIPTION OF THE DISCLOSURE

In the illustrations given, and with reference first to FIGS. 1, 1A and2, the reference numeral 20 designates generally an intermittent urinarycatheter assembly in accordance with the present disclosure. Theintermittent urinary catheter assembly 20 will be seen to comprise acatheter tube 22 having a proximal insertion end 24 and a distal end 26which is located remote from the proximal insertion end 24. The cathetertube 22 has a conventional lumen 28 which extends from at or near theproximal insertion end 24 to the distal end 26 to accommodate thedraining of urine from a human bladder. The catheter tube 22 also has atleast one drainage opening 30 which extends through the catheter tube 22to the lumen 28 in a location at or near the proximal insertion end 24.The catheter tube 22 further has a discharge opening 32 (FIG. 1A)associated with the distal end 26 of the catheter tube 22 to permiturine voided from a human bladder to be discharged therefrom. The urineis discharged through the discharge opening 32 in the catheter tube 22after it passes from the human bladder, through the drainage opening 30,and through the lumen 28. In addition, the intermittent urinary catheterassembly 20 includes a urine discharge sleeve 34 associated with thedischarge opening 32 and having a compact stowed configuration at ornear the distal end 26 of catheter tube 22. In the embodiment shown inFIG. 1, urine discharge sleeve 34 has a compact stowed configuration ator near funnel 40. In the compact stowed configuration, the urinedischarge sleeve may be compacted in any suitable manner. For example,urine discharge sleeve 34 may be folded, bunched, rolled, etc. The urinedischarge sleeve 34 is extendable into a deployed configuration todirect urine flow and to, for example, reach a receptacle such as atoilet at a location spaced from the catheter tube 22 for directingurine to the toilet.

Still referring to FIGS. 1, 1A and 2, the intermittent urinary catheterassembly 20 optionally includes a protective sleeve 36 which covers atleast a portion of the catheter tube 22 and extends from at or near theproximal insertion end 24 toward the distal end 26. While not shown, theprotective sleeve 36 may be secured to an introducer tip, and itpreferably extends to cover substantially the entire insertable portionof the catheter tube 22 to permit contamination-free gripping of thecatheter tube 22 through the protective sleeve 36. The intermittenturinary catheter assembly 22 may include a funnel 40 associated with thedistal end 26 of the catheter tube 22 to define the discharge opening 32through which urine from a human bladder exits the catheter tube 22.

With the foregoing arrangement, the urine discharge sleeve 34 mayinclude a first end 34 a secured to the funnel 40 and a second,extendable end 34 b, and in the stowed configuration, it may beconcertina folded over the funnel 40 as shown in FIG. 1. In addition, aseparate drainage funnel 42 may be provided for extending the second end34 b of the urine discharge sleeve 34 which may be secured to thedrainage funnel 42 in any conventional manner. Preferably, the urinedischarge sleeve 34 may be formed of polyethylene or a material havingsimilar properties, and it may extend to a length of 300 mm or more toprovide for convenient drainage for a wheelchair bound user.

With regard to the first end 34 a of the urine discharge sleeve 34, itmay be suitably secured to the funnel 40, which can be formed of rubber,in any conventional manner, e.g., by heat sealing or the like. Beforethe catheter tube 22 has been inserted into the urethra utilizing theprotective sleeve 36, the drainage funnel 42 may be grasped with onehand to extend the urine discharge sleeve 34 as indicated by the arrowin FIG. 2.

Once the urine discharge sleeve 34 has been substantially fullyextended, the drainage funnel 42 can be placed in or connected to anyurine-receiving receptacle such as a toilet to permit urine voided froma human bladder to be discharged into the toilet after passing from thehuman bladder, through the drainage opening(s) 30, through the lumen 28of the catheter tube 22, through the discharge opening 32 defined by thefunnel 40, through the urine discharge sleeve 34, and through thedrainage funnel 42 into the toilet or other urine-receiving receptacle.

Referring to FIGS. 3-5, the intermittent urinary catheter assembly 20′has certain similarities to the intermittent urinary catheter assembly20 described above in connection with FIGS. 1, 1A and 2. Thus, theintermittent urinary catheter assembly 20′ again comprises a cathetertube 22′ having a proximal insertion end (not shown) and a distal end26′ which is located remote from the proximal insertion end. Thecatheter tube 22′ again has a lumen (not shown) which extends from at ornear the proximal insertion end to the distal end 26′ to accommodate thedraining of urine from a human bladder. The catheter tube 2T also againhas at least one drainage opening (not shown) which extends through thecatheter tube 2T to the lumen in a location which is at or near theproximal insertion end. The catheter tube 22′ also again has a dischargeopening 32′ associated with the distal end 26′ thereof and defined by afunnel 40′ to permit urine voided from a human bladder to be dischargedtherefrom. In addition, the intermittent urinary catheter assembly 20′includes a urine discharge sleeve 34′ associated with the funnel 40′defining the discharge opening 32′ and having a compact stowedconfiguration. Urine discharge sleeve 34′ is extendable into a deployedconfiguration to reach a receptacle such as a toilet.

In common with the embodiment illustrated in FIGS. 1, 1A and 2, theurine discharge sleeve 34′ has a first end 34 a′ secured to the funnel40′ and a second, extendable end 34 b′. However, unlike the embodimentillustrated in FIGS. 1, 1A and 2, the urine discharge sleeve 34′ of theintermittent urinary catheter assembly 20′ illustrated in FIGS. 3-5 isreverse folded in the compact stowed configuration and optionallysecured to the funnel 40′ by a retaining member, for example a band 46′,such as a paper band. Alternatively, the urine discharge sleeve 34′ maybe rolled up in the compact stowed configuration. In addition, a pullring 48′ having an adhesive area 48 a′ (FIG. 5) is secured to the secondend 34 b′ of the urine discharge sleeve 34′.

Referring specifically to FIG. 5, it will be seen that the pull ring 48′may be permanently secured to the second end 34 b′ of the urinedischarge sleeve 34′ as at 48 b′ and the adhesive area 48 a′ maycomprise a releasable adhesive provided on the underside of the pullring 48′ to be exposed when the pull ring 48′ is pulled away from theurine discharge sleeve 34′, as shown.

Before the catheter tube 22′ has been inserted into the urethrautilizing the protective sleeve 36′ and the introducer tip (not shown),the pull ring 48′ may be grasped through the opening 48 c′ utilizing asingle finger on one hand to extend the urine discharge sleeve 34′.

Once the urine discharge sleeve 34′ has been substantially fullyextended into the deployed configuration by pulling as illustrated inFIG. 4, the pull ring 48 can be secured in any urine-receivingreceptacle such as a toilet utilizing the adhesive area 48 a′ to permiturine voided from a human bladder to be discharged into the toilet afterpassing from the human bladder, through the drainage opening, throughthe lumen of the catheter tube 22′, through the discharge opening 32′defined by the funnel 40′, and through the urine discharge sleeve 34′.

Referring to FIGS. 6A-6C, the intermittent urinary catheter assembly 20″also has certain similarities to the intermittent urinary catheterassembly 20 described above in connection with FIGS. 1, 1A and 2. Thus,the intermittent urinary catheter assembly 20″ again comprises acatheter tube 22″ having a proximal insertion end (not shown) and adistal end 26″ which is located remote from the proximal insertion end.The catheter tube 22″ again has a lumen (not shown) which extends fromat or near the proximal insertion end to the distal end 26″ toaccommodate the draining of urine from a human bladder. The cathetertube 22″ also again has at least one drainage opening (not shown) whichextends through the catheter tube 22″ to the lumen in a location whichis at or near the proximal insertion end. The catheter tube 22″ alsoagain has a discharge opening 32″ associated with the distal end 26″thereof and defined by a funnel 40″ to permit urine voided from a humanbladder to be discharged therefrom. Also, the intermittent urinarycatheter assembly 20″ includes a urine discharge sleeve 34″ associatedwith the funnel 40″ defining the discharge opening 32″ and having acompacted stowed configuration. Urine discharge sleeve 34″ is extendableinto a deployed configuration to reach a receptacle such as a toilet.

Unlike the embodiment illustrated in FIGS. 1, 1A and 2 described above,the urine discharge sleeve 34″ comprises part of an adapter assembly 50″(FIG. 6) which includes a fitting 52″ and a drainage funnel 42″. In thisembodiment, the urine discharge sleeve 34″ has a first end 34 a″ securedto the fitting 52″ (FIG. 6C) and a second, extendable end 34 b″ securedto the drainage funnel 42″. The urine discharge sleeve 34″ of theintermittent urinary catheter assembly 20″ illustrated in FIGS. 6A-6C isconcertina folded, in the compact stowed configuration, within thedrainage funnel 42″ portion of the adapter assembly 50″ (FIG. 6) and issecured to both the drainage funnel 42″ and the fitting 52″ in anyconventional manner. The adapter assembly 50″ therefore comprises anassembly which includes the urine discharge sleeve 34″, the drainagefunnel 42″, and the fitting 52″ with the fitting 52″ comprising a nipplehaving a urine passageway which is adapted for insertion into the funnel40″. The fitting or nipple 52″ which is illustrated in FIGS. 6A-6C iscommonly known as a Christmas tree fitting which can be safely securedwithin a structure such as the funnel 40″ at the distal end 26″ of thecatheter tube 22″.

Because the funnel 40″ is typically formed of a rubber or rubber-likematerial, and as a result of the increasing diameter portions 52 a″, 52b″, 52 c″, etc. of the Christmas tree fitting 52″, the user can veryquickly and easily insert the Christmas tree fitting 52″ into the funnel40″ until it is secured at which point the urine discharge sleeve 34″can be extended into the deployed configuration for use by pulling onthe drainage funnel 52″ which is initially disposed over the outersurface of the fitting or nipple 52″ in frictional fit fashion but iseasily separated therefrom (compare FIGS. 6B and 6C).

Referring to FIGS. 6D-6E, an adapter assembly 150″ is illustrated whichis generally the same as the adapter assembly 50″ illustrated in FIGS. 6and 6A-6C with a single exception. As before, the adapter assembly 150″includes a fitting 152″ and a drainage funnel 142″. In this embodiment,the urine discharge sleeve 134″ also has a first end 134 a″ secured tothe fitting 152″ (FIG. 6E) and a second, extendable end 134 b″ securedto the drainage funnel 142″. As before, the urine discharge sleeve 134″of the intermittent urinary catheter assembly 120″ illustrated in FIGS.6D-6E is concertina folded, in the compact stowed configuration, withinthe drainage funnel 142″ portion of the adapter assembly 150″ and issecured to both the drainage funnel 142″ and the fitting 152″ in anyconventional manner. The adapter assembly 150″ therefore again comprisesan assembly which includes the urine discharge sleeve 134″, the drainagefunnel 142″, and the fitting 152″ with the fitting 152″ comprising anipple having a urine passageway which is adapted for insertion into thefunnel 140″. As before, the fitting or nipple 152″ which is illustratedin FIGS. 6D-6E can be safely secured within a structure such as thefunnel 140″ at the distal end 126″ of the catheter tube 122″.

As will be appreciated, the adapter assembly 150″ differs from theadapter assembly 50″ in that a large finger loop 154″ is integrallyformed on the outer surface of the drainage funnel 142″ which makes thedrainage funnel 142″ easy to control even for those users with limitedmanual dexterity when separating it from the fitting or nipple 152″ andextending the urine discharge sleeve 134″ into the deployedconfiguration to reach a toilet as shown in FIG. 6E.

Referring to FIG. 6F, an adapter assembly 250″ is illustrated which isgenerally the same as the adapter assembly 150″ illustrated in FIGS.6D-6E with a single exception. As before, the adapter assembly 250″includes a fitting 252″ and a drainage funnel 242″. In this embodiment,the urine discharge sleeve 234″ also has a first end 234 a″ secured tothe fitting 252″ and a second, extendable end 234 b″ secured to thedrainage funnel 242″. As before, the urine discharge sleeve 234″ isconcertina folded, in the compact stowed configuration, within thedrainage funnel 242″ portion of the adapter assembly 250″ and is securedto both the drainage funnel 242″ and the fitting 252″ in anyconventional manner. The adapter assembly 250″ therefore again comprisesan assembly which includes the urine discharge sleeve 234″, the drainagefunnel 242″, and the fitting 252″ with the fitting 252″ comprising anipple having a urine passageway which is adapted for insertion into thefunnel 240″. As before, the fitting or nipple 252″ which is illustratedin FIG. 6F can be safely secured within a structure such as the funnelat the distal end of a catheter tube.

Also as before, the adapter assembly 250″ has a large finger loop 254″integrally formed on the outer surface of the drainage funnel 242″ whichmakes the drainage funnel 242″ easy to control even for those users withlimited manual dexterity when separating it from the fitting or nipple252″ and extending the urine discharge sleeve 234″ to a toilet as shownin FIG. 6F.

However, unlike the embodiment illustrated in FIGS. 6D-6E, the urinedischarge sleeve 234″ includes a plastic support structure 256″ similarto a coiled spring molded into the concertina folded sleeve but which iscollapsible to be disposed within the drainage funnel 242″ until thedrainage funnel is separated from the fitting or nipple 252″.

Referring to FIGS. 6G-6H, an adapter assembly 350″ is illustrated whichis generally the same as the adapter assemblies 150″ and 250″illustrated in FIGS. 6D-6F with a single exception. In this case, acovered adhesive area 348 a″ (FIG. 6H) is provided on the outer surfaceof the drainage funnel 342″ on the side opposite the large finger loop354″ for adhesively securing the drainage funnel 342″ to a receptaclesuch as a toilet after a protective covering 356″ is peeled away (FIG.6H).

Referring next to FIGS. 6I-6L, an adapter assembly 450″ is illustratedwhich is also generally the same as the adapter assemblies 150″ and 250″illustrated in FIGS. 6D-6F with a single exception relating to thestructure for handling the drainage funnel. In this case, instead of alarge finger loop such as 154″ in FIGS. 6D-6F being integrally formed onthe outer surface of the drainage funnel 442″, a clip style handle 456″is provided for extending the drainage funnel and also for securing thedrainage funnel to a toilet 458″ during use. As shown, a user can insertseveral fingers into the clip style handle 456″ to extend the urinedrainage sleeve 434″ into the deployed configuration (FIG. 6J) and theclip style handle 456″ can then be spread open to clip the drainagefunnel 442″ to the toilet 458″ as shown in FIG. 6L.

Referring to FIGS. 7 and 8, the intermittent urinary catheter assembly20′″ also has certain similarities to the intermittent urinary catheterassembly 20 described above in connection with FIGS. 1, 1A and 2. Thus,the intermittent urinary catheter assembly 20′″ again comprises acatheter tube having a proximal insertion end and a distal end which islocated remote from the proximal insertion end. The catheter tube againhas a lumen which extends from at or near the proximal insertion end tothe distal end to accommodate the draining of urine from a humanbladder. The catheter tube also again has at least one drainage openingwhich extends through the catheter tube to the lumen in a location whichis at or near the proximal insertion end. The catheter tube also againhas a discharge opening 32′ associated with the distal end thereof anddefined by a funnel 40′ to permit urine voided from a human bladder tobe discharged therefrom. Also, the intermittent urinary catheterassembly 20′″ includes a urine discharge sleeve 34′″ associated with thefunnel 40′″ defining the discharge opening 32′″ and extendable to areceptacle such as a toilet.

Like the embodiments illustrated in FIGS. 6 and 6A-6L, and unlike theembodiment illustrated in FIGS. 1, 1A and 2, the urine discharge sleeve34′″ comprises part of an adapter assembly 50′ which includes a fitting52′″. In this embodiment, the urine discharge sleeve 34′ has a first end34 a′″ secured to the fitting 52′″ and a second, extendable end 34 b′″.The urine discharge sleeve 34″ of the intermittent urinary catheterassembly 20′″ illustrated in FIGS. 7 and 8 is reverse folded in thecompact stowed configuration and secured to the fitting 52′″ by aretaining member 46″, for example a band, such as a paper band, and thisadapter assembly 50′ is comprised of the urine discharge sleeve 34′, thefitting 52′″ and the band 46″ with the fitting 52′″ comprising a nipplehaving a urine passageway which is adapted for insertion into the funnel40′. The fitting or nipple 52′″ illustrated in FIGS. 7 and 8 can besafely secured within a structure such as the funnel 40′″.

Because the funnel 40′″ is typically formed of a rubber or rubber-likematerial, and as a result of the increasing diameter portions 52 a′″, 52b′″, 52 c′″, etc. of the fitting 52′″, the user can very quickly andeasily insert the fitting 52′″ into the funnel 40′″ until it is securedat which point the urine discharge sleeve 34′″ can be extended for use.

In this connection, a pull tab 48′″ having an adhesive area 48 a′″ issecured to the second end 34 b′″ of the urine discharge sleeve 34′″ tobe used in extending the discharge sleeve 34′″ into the deployedconfiguration and adhesively securing the second end 34 b′″ to areceptacle such as a toilet.

With regard to the two embodiments illustrated in FIGS. 3-5 and 7-8,respectively, it will be appreciated that when the user pulls on thepull ring 48′ or the pull tab 48′, it releases the folded urinedischarge sleeves 34′ and 34′ from the paper bands 46′ and 46′,respectively.

As will be appreciated, the embodiments illustrated in all of FIGS. 6,6A-6L, 7 and 8 give

users of conventional intermittent urinary catheters the option of beingable to extend the point from which urine is discharged from aconventional intermittent urinary catheter by purchasing an adapterassembly which quickly and easily connects to the funnel of the catheterand is quickly and easily extendable by pulling on the extendable end ofa urine discharge sleeve.

Advantageously, all of the urine discharge sleeves can be extended totheir full length suitably ranging from about 300 mm to about 430 mm toallow the user to administer self intermittent catheterization whileremaining seated in a wheelchair during the procedure. Because of thelength of the urine discharge sleeves, urine voided from a human bladderthrough an intermittent urinary catheter can be directed into areceptacle such as a toilet by causing the urine exiting the catheter topass through the urine discharge sleeves.
